摘　　要：依据南里海盆地中15个大油气田的资料,应用研究含油气系统的思路与方法,对盆地构造沉积演化及油气地质条件进行剖析,探讨了大油气田的形成条件和分布特征。研究认为,南里海盆地主要发育麦考普组-红层组含油气系统,盆地北缘的大型走滑挤压构造带的油气地质条件最为优越,目前已发现的大油气田集中分布在该构造带上。里海东西两侧岸线附近的褶皱带也具备良好的生储盖条件,有望成为盆地今后油气勘探的有利区带;麦考普组-红层组含油气系统比较年轻,油气的生、运、聚活动仍然活跃,因此,即使是目前勘探程度较高的北缘构造带,仍然具有较大的勘探潜力。Based on the data from the 15 giant fields and by means of petroleum system analytical method,the tectonic and depositional evolutions and petroleum geologic conditions in the South Caspian basin are discussed.The research shows that most reserves of the basin are from the Maykop-Red Bed petroleum system,the large-sized strike-slip compaction structural belt in northern margin of this basin is in the most advantageous petroleum geologic conditions.The giant fields that have been found are typically located in this the structural belt.The fold belts along both the west and the east coastlines of the Caspian alo have good petroleum geologic conditions of source,reservoir and cap rocks,being helpful to be the favorable areas for future exploration.The Maykop-Red Bed formation is a young petroleum system,the generation and migration and accumulation of the hydrocarbon are still active.So,even the structural belt with high degrees of exploration in the northern margin of this basin still has a greater potential for petroleum exploration.
